create alias inside (183936) -> indoors_viewpoint (0)

create alias inside_viewpoint (0) -> indoors_viewpoint (0)

Reason: Makes it more clear what the tags actually mean.

And I got this error:

Error: Antecedent name has already been taken (create alias outdoors -> outdoors_viewpoint), Error: Antecedent name has already been taken (create alias indoors -> indoors_viewpoint)

You need to remove the existing aliases first, of which both outside and inside have several.

Since there are only two tags and no other complications, it would probably be simpler to just create two separate threads with regular alias requests. Unlike BURs, those can handle transitives.

That's more than I know how to do, if someone could do it for me, I'd appreciate.
